Answer:
c. Economies of scope
Step-by-step explanation:
In business, economies of scope refers to producing more than one product or service because you can earn higher profits by diversifying your production. The cost of producing these products together or one after another is lower or yields more benefits than producing them separately.
In agriculture economies of scope refers to producing as many different crops as you can on the same fields. In the case of soybean and corn (or wheat), the crops are rotated because each crop required different nutrients from the soil.
